Tankless Flush and Maintenance Check
Tankless flush and maintenance check while buttoning up overall setup
Flushed the heat exchanger on this Navien NPE-240A (NG). Looks like it had been a little while based on the sludge showing up in the water bucket. While there, we also added expansion tank (securely strapped to the wall), two shutoff valves, and a drain to the tankless setup.
